Abstract: The extraction and separation of Cu(II) and Fe(III) from HCl media using Cyanex 921 in kerosene were investigated. The effect of shaking time, aqueous phase acid concentration, Fe(III)/Cu(II) concentration, Cyanex 921 concentration, temperature and aqueous to organic phase ratio on the separation of Cu(II) and Fe(III) was studied using 0.1 mol/L Cyanex 921 in kerosene. Maximum separation was achieved from 2 mol/L HCl containing 0.001 mol/L Cu(II) and 0.005 mol/L Fe(III) with 0.1 mol/L Cyanex 921 in kerosene. Feasible separation of copper and iron was also possible from 5 mol/L HCl using 0.02 mol/L Cyanex 921.
